Multipartite quantum systems and symplectic toric manifolds
Hoshang Heydari
In this paper we study the geometrical structures of multi-qubit states based on symplectic toric manifolds. After a short review of symplectic toric manifolds, we discuss the spac…
Ultracold atoms in a cavity mediated double-well system
Jonas Larson, Jani-Petri Martikainen
We study ground-state properties and dynamics of a dilute ultracold atomic gas in a double well potential. The Gaussian barrier separating the two wells derives from the interactio…
Arbitrarily High Super-Resolving Phase Measurements at Telecommunication Wavelengths
Christian Kothe, Gunnar Björk, Mohamed Bourennane
We present two experiments that achieve phase super-resolution at telecommunication wavelengths. One of the experiments is realized in the space domain and the other in the time do…
Circuit QED scheme for realization of the Lipkin-Meshkov-Glick model
Jonas Larson
We propose a scheme in which the Lipkin-Meshkov-Glick model is realized within a circuit QED system. An array of N superconducting qubits interacts with a driven cavity mode. In th…
